Hussmann Interview Questions and Answers

Power factor is a measure of how effectively electrical power is being used in a circuit.

• Power factor is the ratio of real power (watts) to apparent power (volt-amperes) in an AC circuit.

• It ranges from 0 to 1, with 1 indicating all power is being used effectively.

• A low power factor can result in increased energy costs and inefficient use of power.

• Power factor correction techniques, such as adding capacitors, can improv...read more

A breaker is a device designed to protect an electrical circuit from damage caused by overload or short circuit.

• A breaker automatically interrupts the flow of electricity when it detects an overload or short circuit.

• There are different types of breakers such as circuit breakers, fuse boxes, and ground fault circuit interrupters (GFCIs).

• Breakers are essential for preventing electrical fires and protecting electrical equ...read more

Refrigeration cycle is a thermodynamic process used to transfer heat from a low-temperature region to a high-temperature region.

• The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.

• The refrigerant absorbs heat from the low-temperature region in the evaporator and releases it in the high-temperature region in the condenser.

• Applications include air conditioning, refrigeration...read more
